I'm trying to visulize a model currently but found less efficient in fps.

Before I pass the model to art designer to make it more batch-friendly, I've got no idea about the relationship about relationship between 'hardware specification' and 'maximum geometry input', here's how I summarize (assuming there's no texture change):

1. I understand the CPU clock can determine the maximum batch number, but what will it be exactly like?

2. What can determine the maximum vertices number in one batch? How can I figure it out? (The art designer needs to know before optimization).

3. Can I understand the relationship between batch and effiency like "An excess of batch number or vertices number in one batch over hardware limitation will both descend the frame rate"?

Many thanks!
